IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 168,931, dated October19, 1875; application filed August 6, 1875.

To all whom it may concern.-

Be it, known that I, IRVIN A. SHAW, of Grand Meadow, in the county ofMower and State of Minnesota, have invented a new and useful Improvementin Washing-Machines, of

which the following is a specification:

Figure l is a vertical section of my improved machine, taken through theline so a; of Fig. 2. Fig. 2 is a top view of the same, part of theupper roller and of the endless apron being broken away. Fig. 3 is adetail view of the device for holding the upper roller down to its work.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved washing machine,simple in construction, convenient in use, easily operated, andeffective in operation, washing the clothes quickly and thoroughly, andwithout injuring them.

The invention consists in the combination of the rollers, the springs,and the endless apron, provided with hooks, with each other, and withthe semi-cylindrical suds-box, as hereinafter fully described.

A is the suds-box of the machine, which is made with vertical sides andends, and a semicylindrical bottom. The suds-box A is supported by legsB, of such a length as to raise the machine to a convenient height. 0are two small rollers, which are made with alternate swells andcontractions, which are so arranged that the swells of the one rollermay fit into the contractions of the other roller, as shown in Fig. 2.The rollers C have pivots at their ends, the pivots at one end workingin sockets in the inner surface of one side of the suds-box A, and thepivots at the other end working in the lower ends of vertical grooves inthe inner surface of the other side of said suds-box A, so that the saidrollers O can be readily detached when desired. D is a larger roller,which is corrugated longitudinally, placed above the rollers G, and thejournals of which revolve in vertical slots in the sides of the suds-boxA. The roller D is held down to its work by rubber or other springs E,the lower ends of which are connected with the sides of the suds-box Aby staples or other fastenings e, and their upper ends are provided withbooks 0 to hook upon the journals of the upper roller D. To one of thejournals of the roller D is attached the crank F, by which the machineis operated.

G is an endless apron or band, made of cloth,

and passed around the lower rollers U. The apron G is kept spread bystretchers g of \vhalebone or other material, attached to ittransversely. To the endless apron G are attached hooks 9 to receive theclothes.

By this construction the clothes are alternately drawn through thewater, and'then between the rollers O D, and are thus washed clean veryquickly and without being injured.

Having thus described my invention. I claim as new and desire to secureby Letters Patent The combination of the rollers O O D, the springs E,and the endless apron Gr, provided with stretcher-s g and hooks 9 withthe semicylindrical suds-box A, substantially as herein shown anddescribed.
